Sweet. I am in the middle of a Six13 build myself for a race bike. Its going slow but buying off local CL and Ebay take time and I am trying to not buy anything brand new. I am hoping to complete the build in under $1500 (without wheelset) and be in the range of 15 to 15 1/4 lbs.

What I meant by "workup" was an estimate of cost and component weight; I copied someone's post about their build and made a quick spreadsheet to keep track of costs and figure out the weight. Its pretty cool to have on hand as you decide on your parts and doubles as a good document to have for insurance purposes.
